Answer Posted / kapil pandey
In AC- P = Root3 *V*I (for 3 phases) [ 3 core windings]
In DC - P= 3*V*I (for 3 phases)[6 core windings]
means for getting power sqroot3 times we have to wound
double. making the DC motor size bigger.
one more thing that the loss arresting system & protection
system shall also be bigger in case of DC.

Sir, My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs. Sir, My question now when my mind strikes with 2 options 1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or 2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2 Please suggest me sir
